It sounds wrong because a larger sprocket with 45 teeth (same as stock) would have a different pitch between the teeth. Therefor, improperly sized against a stock pitched chain. This is why the number of teeth increase when the physical diameter of the sprocket is larger, vice versa for smaller sprockets.

Bottom line, you're gunna wear out the chain, sprocket or both. Also, it will cause premature wear on your front sprocket as well. Any chance it has more teeth than 45 and you mistyped what you meant? It's easy to check, JT sprockets stamps the number of teeth right on the sprocket. Look for a 40 something number etched into the metal.
